Abstract: A part mounting mechanism includes a boss, and a resin clip adapted to be assembled to the boss. The resin clip includes holding pieces, elastic engagement pieces, and a connecting portion. The part mounting mechanism also includes projecting portions formed on facing inner surfaces of the connecting portion at predetermined intervals in a staggered fashion along a direction in which the boss is inserted. When the boss is inserted into the connecting portion, the projecting portions bite into the distal end portion of the boss.

Abstract: A part mounting mechanism includes: a boss; and a resin clip, adapted to be assembled to the boss, including: holding pieces; elastic engagement pieces; and a connecting portion; and projecting portions formed on facing inner surfaces of the connecting portion at predetermined intervals in a staggered fashion along a direction in which the boss is inserted wherein: the resin clip is formed of a resin material which is harder than the boss; a space defined between a distal end of the projecting portion provided on one the inner surfaces and a distal end of the projecting portion provided on the other inner surface as viewed in the boss inserting direction becomes smaller than a thickness of a distal end portion of the boss; and when the boss is inserted into the connecting portion, the projecting portions bite into the distal end portion of the boss.
